The first is a technical demo of Sapphire. The second is a process talk relating experience of moving Sapphire to open source.

If you are planning on attending EclipseCon this year and want to hear me talk about Sapphire in person, make sure to leave your comments on the talk for the program committee. There are far more submissions than there are slots every year, so comments from potential attendees are valuable in helping the program committe make their selections.
